项目摘要

The functions of the Cryopreservation and Embryo Derivation Core are: A) to expeditiously transfer mutant mice created by the Osaka group in Japan to the La Jolla group. B) to rederive frozen embryos shipped from La Jolla to Osaka. C) to generate ES cell-derived chimeric mice for the establishment of knockout mice by microinjection of ES cells into mouse blastocysts and implantation. D) to submit mutant mouse strains to the MMRRC for distribution to the scientific community. Generation of mouse models have made major contributions to recent advances in the field of innate immunity. In the proposed project to investigate anti-viral immune responses by both forward and reverse genetics, close collaboration between the La Jolla group (conducting mouse forward genetics) and the Osaka group (conducting mouse reverse genetics) will be essential for success. We will exchange mutant mice and will study them in parallel using different viruses. We will also analyze signaling pathways based on the outcome of experiments in which ENU-induced mutations and knockout mutations are combined. A rapid and safe means of exchange, circumventing quarantine and allowing quick assessments, will be provided by this Core. The Core will also be responsible for the microinjection of ES cells into mouse blastocysts and re-derivation from the embryos for generating knockout mice. Finally, the Core will also send mutant mouse strains generated in Osaka to the MMRRC for distribution to the scientific community, permitting accelerated research in many laboratories worldwide.

冷冻保存和胚胎衍生核心的功能是： A) 快速转移突变体日本大阪小组和拉霍亚小组创造的小鼠。 B) 重新获得从洛杉矶运来的冷冻胚胎乔拉飞往大阪。 C) 产生ES细胞衍生的嵌合小鼠，用于建立敲除小鼠将 ES 细胞显微注射到小鼠囊胚中并植入。 D) 将突变小鼠品系提交给 MMRRC 分发给科学界。小鼠模型的产生取得了重大进展对先天免疫领域最新进展的贡献。在拟议的抗病毒研究项目中正向和反向遗传学的免疫反应，拉霍亚小组之间的密切合作（进行小鼠正向遗传学）和大阪小组（进行小鼠反向遗传学）将成功的关键。我们将交换突变小鼠并使用不同的病毒并行研究它们。我们还将根据 ENU 诱导突变的实验结果分析信号通路和敲除突变相结合。一种快速、安全的交换方式，规避检疫和该核心将提供允许快速评估的功能。核心还将负责将 ES 细胞显微注射到小鼠囊胚中并从胚胎中重新衍生以产生敲除老鼠。最后，核心还将把在大阪产生的突变小鼠品系发送到 MMRRC 进行分发科学界，允许在世界各地的许多实验室加速研究。
